Lumens = --
When working with lighting specifications, converting millicandela (mcd) to lumens (lm) can be important for understanding the total light output of a source. A Millicandela to Lumens Calculator makes this process simple and efficient, especially for LEDs and other focused light sources.
What Are Millicandela and Lumens?
- Millicandela (mcd) measures the intensity of light emitted in a specific direction, commonly used for LEDs.
- Lumens (lm) represent the total light output in all directions from a light source.
The two units measure different aspects of light, and the conversion depends on the beam angle of the light source.
How to Convert Millicandela to Lumens
To convert millicandela to lumens, you need the following formula:
Lumens = (Millicandela × Beam Angle Factor) ÷ 1000
Here’s how it works:
- Millicandela (mcd) is divided by 1000 to get candela (cd).
- Beam Angle Factor is calculated based on the beam angle. A narrow beam angle concentrates light, increasing the perceived intensity (candela) for the same lumen output.
Example Calculation
- A 5000 mcd LED with a 30° beam angle has an approximate beam angle factor of 0.079.
- Lumens = (5000 × 0.079) ÷ 1000 ≈ 0.395 lumens.
Why Use a Millicandela to Lumens Calculator?
- Precision: It simplifies the complex math involved in the conversion.
- Accurate Design: Helps ensure the right lighting for applications like displays, task lighting, and indicators.
- Ease of Comparison: Quickly compare LEDs and other lights with different specifications.
Conclusion
A Millicandela to Lumens Calculator is a valuable tool for lighting designers, engineers, and hobbyists. It ensures accurate conversions, enabling better decisions when selecting or designing light sources. Whether for home projects or professional applications, this calculator makes lighting design straightforward and efficient.
